(D) Read the following passage and answer the questions.
Prevention is better than cure. It is recognised that the only way to get nd of
malaria completely is to get rid of the mosquitoes, which cause it. Malaria is
always associated with damp and marshy land. This is not because the land is
damp. but because the standing water is the breeding place of the mosquito, which
begins its life as larvae living in the water. Malaria does not frequently occur in dry
desert countries because mosquitoes cannot breed there. The only way to destroy
mosquitoes is to prevent their breeding in standing water. This can be done hy
draining all ponds and pools; and by keeping them covered in the breeding season
with a film of kerosene oil, which kills the larvae by depriving them of air.

Answers
Answer:
1)a)Stay somewhere that has effective air conditioning and screening on doors and windows. ...
b)If you're not sleeping in an air-conditioned room, sleep under an intact mosquito net that's been treated with insecticide.
c)Use insect repellent on your skin and in sleeping environments.
2)Malaria mosquito breeding grounds include fresh water or salt-water, vegetative or non-vegetative, shady or sunlit. Ground pools, small streams, irrigated lands, freshwater marshes, forest pools, and any other place with clean, slow-moving water are all considered prime Malaria mosquito breeding grounds for egg-laying.
3)1)Don't let water stagnate: Mosquitoes breed by laying eggs in stagnant water. ...
Clear the litter: 2)Do not allow any debris to collect around your house, especially in gardens, compounds, or yards.
4)Temperature is particularly critical. For example, at temperatures below 20°C (68°F), Plasmodium falciparum (which causes severe malaria) cannot complete its growth cycle in the Anopheles mosquito, and thus cannot be transmitted.
5)Tending to prevent; preventative.
